Abstract
A method and system is used to process slag material to yield by-products including a finished iron rich product and a finished low iron fines product. The by-products may include a finished high iron product and a finished medium iron product. The method and system include size classifying the material into a plurality of sized groups prior to using magnetic separation to separate at least one of the sized groups into two portions having differing magnetic susceptibilities. The method and system may include more than one phase of size classifying the material into a plurality of sized groups and using magnetic separation to separate at least one of the sized groups into portions, where the average size of the material remaining after one phase is reduced prior to the subsequent phase.
